Solar System only have 8 Planets now...

[vseehua]

As of now, Astronomers had agreed to remove the designation of Pluto as a planet. To put it in laymen terms, Pluto is no longer classified as a planet now...

So, the solar system as we know will only have eight planets up till Neptune.

Pluto shouldn't have been classified as a planet anyway, it's a part of Kuiper Belt (http://en.wikipedia.org/wiki/Kuiper_Belt).

and who the fish cares?

This is the outcome when you get a bunch of scientist with no real job together in a room.

poor pluto (and it's companion Charon)

But it's better than adding Ceres, Xena and etc etc into the text books =.= haha

Wow it's been two years?! It felt like just a few months ago when there were nine planets.

Well, my guess is that a formal definition of a planet will clear up all the confusion regarding future discoveries of future bodies/objects. Imagine if every dwarf planet is classified as a planet, then we would have 13 planets in our solar system!

Although, aside from better categorizing, I can't really think of a reason for a formal definition of planets.

13? There are much more objects in the Kupier Belt than those objects :P if the old definition persists, we might soon have to deal with >100 "planets."

Well, for now, it's eight planets. Have our textbooks made the amendments?
